3、Silane Coupling Agent
Silane coupling agents are primarily used in reinforced plastics and electric cables composed of crosslinked polyethylene. Other uses include resins, concrete, sealant primers, paint, adhesives, printing inks and dyeing auxiliaries.
4、Silane Coupling Agents
Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.
Silane coupling agent
Silane Coupling Agents are bifunctional organosilicon compounds with the general formula Y-R-SiX3. In this structure, the X group (typically alkoxy) hydrolyzes to form silanols that bond to inorganic surfaces, while the Y organofunctional group (e.g., amino, epoxy, vinyl) bonds with organic polymers.
Solutions for the Rubber Industry
By off ering silane treated silicas, i.e. COUPSIL®, Evonik pro-vides a solution to shorten the compounding process without performance loss. COUPSIL® products are available for sulfur and peroxide cured compounds and may be used directly or in a blend with untreated silica.
Silanes for the Rubber Industry
Our range covers liquid silanes, solid blends with carbon black as well as a line of white COUPSIL types. The latter are precipitated silica that have been pre-reacted with silane.
Dynasylan®
Serving as coupling agents, surface modifiers, and adhesion promoters, DYNASYLAN® silanes stand out for their superior performance, tailored effects, high purity, and consistent quality.
Silanes for adhesives and sealants
And with good reason: organofunctional Dynasylan® products improve adhesion, cohesion and drying. In addition, they can be used for reinforcement and endcapping. It is these essential properties that allow adhesives and sealants, when exposed to moisture or applied to particularly diffi cult surfaces, to be as eff ective as we know them today.
COUPSIL® products – pre
A further advantage of the silatrane is to be a VOC-free coupling agent, which can simplify curing (e.g. pressure-less salt-bath or hot air curing) and leads to smooth vulcanizates.
